No symptoms, am I still pregnant?!

Ka
Hey mamas, Im hoping to get an encouraging word... 17 wks today and the past week and half, my preggo symptoms have faded. Breasts shrunk (a little) and belly fat loosening. My symptoms were SO bad, It seems wierd. I just need some assurance this is normal?? Ive got another 2 wks until my anatomy scan, and I dont want to be plagued in doubt. 
Thanks!!
